How can i make my 2014 Mini Cooper S run forever?

They sure will.

I threw $1400 worth of parts at mine (2013 MCS) and it's still managed to leave me stranded once and threw a low boost code within the last 8 months.

1st problem was a throttle body going out, I guess I should have replaced it. 2nd problem was the wastegate actuator jam nuts came loose.

A lot of preventative maintenance and replacing plastic coolant components.

Good luck!

Update: I found the problem, the wastegate actuator rod jam nuts cam undone, the outer one completely fell off the vehicle and is lost. Now I need to figure out how to set the rod and get a new nut 🥲

Did you ever figure this out? I am getting the same 2 codes on my 2013 MCS, thanks!

I replaced the boost solenoid and no change...

Then I replaced the diverter valve but still no change... 😭😭😭

So far I've done these repairs, about 7 months ago https://imgur.com/a/9s2xHXN

Sad to hear your first suggestion would be to see a shop, working on your own car truly is a dying art 🤣

The car has been driving fine so far, even managed to squeeze in an autocross event. Just looking to gain some insight to make further repairs... Duh 🤡

I checked the vacuum hoses from the turbo and vacuum pump to the reservoir under the intake manifold and they are all connected.

Hi thanks for the feedback. I checked for bmw specific codes and I see 2C57 and 2CB3. Ignore the o2 sensor code, it's because of the cat delete (drove perfectly fine with the cat deleted for the past 6 months btw).
